摘要： Methods, systems, and computer-readable media of columnar storage of a database index are disclosed. A particular columnar index includes a column store that stores rows of the columnar index in a column-wise fashion and a delta store that stores rows of the columnar index in a row-wise fashion. The column store also includes an absence flag array. The absence flag array includes entries that indicate whether certain rows have been logically deleted from the column store.

摘要： A computer system includes a memory and a processor coupled to the memory. The processor is configured to execute instructions that cause execution of an in-memory database system that includes one or more database tables. Each database table includes a plurality of rows, where data representing each row is stored in the memory. The in-memory database system also includes a plurality of indexes associated with the one or more database tables, where each index is implemented by a lock-free data structure. Update logic at the in-memory database system is configured to update a first version of a particular row to create a second version of the particular row. The in-memory database system includes a non-blocking garbage collector configured to identify data representing outdated versions of rows.

摘要： A method for performing a consistency check on a database backup of a database is performed without requiring a full recovery of the original database from the database backup. Instead, a database view may be used as a smaller storage requirement tool for providing a transaction-consistent view of portions of an existing full database backup. The database view, in combination with the database backup and transaction log, contains all the information necessary to perform a consistency check on the database backup without a full reconstitution of the original database from the database backup. The consistency check may be run on the database view along with the database backup to verify the integrity of the full database backup to add improved reliability to a database recovery scheme.

摘要： Systems (and corresponding methods) that unbundle the kernel or storage engine of a database system are provided. The unbundling separates transactional aspects from storage aspects. The two components of the storage engine resulting from the unbundling are a transaction component (TC) and a data component (DC). Data storage access methods are implemented in the DC without the added complexity of dealing with transactions, which are handled separately in the TC. The interface supported by the DC is a logical interface, e.g., record oriented, in which the way that records are mapped to disk pages (or flash memory blocks, etc.) need not be exposed. The TC then deals with logical locking and logging, meaning that it need know nothing about the way pages are used in the DC.
摘要翻译：提供了解除数据库系统的内核或存储引擎捆绑的系统（和相应的方法）。拆分将交易方面与存储方面分开。由分拆产生的存储引擎的两个组件是事务组件（TC）和数据组件（DC）。数据存储访问方法在DC中实现，而不需要在TC中单独处理的事务处理更多的复杂性。由DC支持的接口是逻辑接口，例如面向记录，其中记录被映射到磁盘页（或闪存块等）的方式不需要被暴露。 TC然后处理逻辑锁定和记录，这意味着它不需要知道在DC中使用页面的方式。
